Does TimberTech decking require pre-drilling to install?

TimberTech AZEK products do not require pre-drilling.

For TimberTech PRO and EDGE decking, there are a few instances when you will need to pre-drill. Cortex fasteners require a 3/16’’ pre-drill. If you are using TimberTech TOPLoc fasteners or an alternative composite deck screw, then pre-drilling is required when within 1 ½” of the ends of the boards, as well as for installation in temperatures below 45 degrees Fahrenheit. This is to help avoid splitting the board and screw shearing. For more information, be sure to check out our Decking Installation Guide.
